bivarRIpower-package:
Sample size calculations for bivariate longitudinal data
Description
Provides function to carry out sample size calculations for correlations that occur between random intercepts, residuals, and observations
in a bivariate longitudinal model. Maximum likelihood estimates are used for correlation variances. Sample size is calculated under
one-sample z-test framework. Details of calculations are given in Comulada and Weiss (2010).
